[0001] This application relates to the field of smart wearable technologies, and particularly to a ring shell and a smart ring. Background Art

[0002] With the continuous progress of smart wearable technologies, smart rings have been widely welcomed by consumers due to their unique wearing methods and portability. However, traditional smart rings can only be used in a single wearing method, which to a certain extent limits their usage diversity and convenience, and traditional smart rings cannot meet the diverse wearing needs of users.

[0003] Currently, there are some smart ring designs in the market that attempt to solve this problem, but they usually have problems such as complex structures, high manufacturing costs, and poor wearing comfort. These designs often require a large number of modifications to the ring body, which not only affects the aesthetics of the ring but may also have an adverse impact on the overall structure and stability of the ring.

[0004] Therefore, based on the above problems, the prior art needs to be improved. Summary of the Utility Model

[0005] The purpose of this application is to achieve diverse wearing methods and provide a good wearing experience.

[0006] The above technical purpose of this application is achieved through the following technical solutions: A ring shell includes an outer frame and an inner ring. The outer frame and the inner ring are detachably connected. A cavity is formed between the outer frame and the inner ring for accommodating electronic components. Mounting members are provided on opposite sides of the outer frame for mounting watchbands. The mounting members are hollow and provided with mounting channels. The inner wall of the mounting channel is hollowed out with avoidance openings for avoiding the watchbands mounted into the mounting channels.

[0007] By adopting the above technical solutions, the detachable design of the outer frame and the inner ring facilitates the repair, replacement, or upgrade of the internal electronic components, extends the service life of the product, and reduces the usage cost. The formed cavity provides a stable and safe accommodation space for the electronic components, effectively protecting the components from the influence of the external environment and ensuring the normal operation and stable performance of the smart ring. The mounting members on both sides of the outer frame and the hollow mounting channels therein provide a convenient and stable connection method for the installation of the watchbands, enabling the ring to be worn on the wrist like a watch, expanding the wearing methods and usage scenarios. The avoidance openings on the inner wall of the mounting channel can prevent the watchbands from being obstructed during installation, ensuring the smooth installation of the watchbands, improving the installation efficiency and convenience. It makes the smart ring more innovative and unique in appearance, meeting the pursuit of consumers for personalization and fashion.

[0008] Optionally, the outer frame is provided with a first notch, and the inner ring is provided with a second notch at a corresponding position, the outer frame is provided with first clips at both ends close to the first notch, and the inner ring is provided with second clips at both ends close to the second notch, and the first clip and the second clip are engaged with each other.

[0009] By adopting the above technical solution and the matching design of the clip-on, the outer frame and the inner ring are precisely connected, ensuring the stability of the connection between the two and reducing the risk of separation or loosening during use. The clip-on connection method is simple and efficient, easy to assemble and disassemble, and conducive to production and subsequent maintenance. The clip-on structure helps to improve the sealing between the outer frame and the inner ring, and better protect the internal electronic components from external factors such as dust and water vapor. The precise clip-on fit can ensure the coaxiality and concentricity between the outer frame and the inner ring, making the overall structure of the ring more regular and more comfortable to wear. When the internal electronic components need to be replaced or repaired, the outer frame and the inner ring can be quickly opened by separating the clip-on, which improves the convenience and efficiency of operation.

[0010] Optionally, a positioning groove is provided along the setting direction of the outer frame, and a positioning boss is provided at a corresponding position of the inner ring, and the positioning groove and the positioning boss are matched for positioning.

[0011] By adopting the above technical solution, the cooperation of the positioning groove and the positioning boss can ensure that the outer frame and the inner ring are aligned quickly and accurately during assembly, thereby improving assembly efficiency and accuracy. Accurate positioning can avoid deviation or misalignment between the outer frame and the inner ring during the connection process, thereby ensuring the integrity and stability of the ring shell structure. This positioning structure helps to enhance the tightness of the connection between the outer frame and the inner ring, and reduce the relative displacement caused by vibration or external force during use. Effective positioning enables the outer frame and the inner ring to share the load evenly when subjected to force, thereby extending the service life of the ring shell. For mass production, the presence of the positioning structure can ensure product consistency, improve product quality and yield rate. When disassembly and reassembly are required, the positioning structure can be used as a reference to facilitate operation and reduce the possibility of incorrect assembly.

[0012] Optionally, a stop structure is provided on the inner ring, and the stop structure abuts against the inner wall of the outer frame to play a role of limiting protection when being squeezed.

[0013] By adopting the above technical solutions, the stopping structure can effectively limit the excessive displacement of the inner ring under external force extrusion, thereby protecting the internal electronic components from damage and enhancing the impact resistance of the ring. When the ring is subjected to accidental strong extrusion, the stopping structure can prevent the inner ring from being excessively deformed, maintain the structural stability of the ring shell, and extend its service life. The stopping structure that plays a limiting and protecting role helps to maintain the relative positional relationship between the inner ring and the outer frame, ensuring the normal functioning of the ring. It can reduce the friction and wear between the inner ring and the outer frame caused by extrusion, reduce the frequency of maintenance and replacement of parts, and save the usage cost. It improves the reliability and durability of the ring in various complex usage environments, making users feel more at ease when using it.

[0014] Optionally, the outer frame and the inner ring are detachably connected by a magnetic attraction method, and corresponding magnet blocks are respectively arranged on the outer frame and the inner ring.

[0015] By adopting the above technical solutions, the magnetic attraction connection method is easy to operate, without the need for complex tools or steps. Users can easily disassemble and assemble the outer frame and the inner ring, improving the convenience of use. The attraction of the magnet blocks can ensure that the outer frame and the inner ring are firmly connected when connected, and are not easily separated accidentally, ensuring the integrity and stability of the ring structure. This connection method does not affect the appearance of the ring, maintaining its beauty, and at the same time avoiding the protruding parts or gaps that may appear in the traditional connection method. It is convenient to quickly replace the inner ring or the outer frame to meet the user's needs for different colors, materials or styles, increasing the personalization and diversity of the product. During maintenance and repair, the outer frame and the inner ring can be quickly disassembled, facilitating the inspection and cleaning of the internal electronic components. The magnetic attraction connection is relatively gentle, reducing the wear and damage that may be caused to the components by actions such as plugging and unplugging, and extending the service life of the product.

[0016] Optionally, the outer frame is a hollow structure, enclosing a cavity, and the cavity is filled with an elastic member.

[0017] By adopting the above technical solution, the hollow structure is combined with the elastic member inside the cavity, which can effectively absorb and buffer the external impact force, provide better protection for the internal electronic components, and reduce the risk of component damage caused by collision or vibration. The filling of the elastic member increases the anti-deformation ability of the outer frame, making the outer frame not easily undergo permanent deformation when subjected to external forces, maintaining the aesthetic appearance and structural integrity of the ring. This structure helps to reduce the overall weight of the ring, improve the wearing comfort, and reduce the burden on the finger. The hollow structure combined with the elastic member can improve the feel of the ring, making it softer and more comfortable when touched and worn. When the ring is subjected to temperature changes, the cavity and the elastic member can play a certain role in heat insulation and buffering, reducing the impact of temperature on the internal electronic components and ensuring their normal operation. For the transmission of sound and vibration, this structure can play a certain role in blocking and attenuation, reducing the interference of external noise on the sensors or other components inside the ring.

[0018] Optionally, an installation groove for accommodating electronic components is provided on the inner surface of the outer frame close to the cavity, and a buffer insulating pad is provided in the installation groove.

[0019] By adopting the above technical solution, the specially provided installation groove provides a clear and fixed installation position for the electronic components, ensuring a reasonable and neat layout of the components in the ring, and reducing the risk of circuit connection problems or damage caused by random movement of the components. The buffer insulating pad in the installation groove can further buffer the external impact force and vibration, provide additional protection for the electronic components, and enhance their stability and reliability during use. The buffer insulating pad has insulating properties, which can effectively prevent short circuits between electronic components and improve the safety and stability of the circuit. This design helps to improve the thermal isolation effect between the electronic components and the outer frame, avoiding the direct influence of the temperature change of the outer frame on the working performance of the components. It is convenient for the installation and fixation of components during the production and manufacturing process, improves production efficiency, and ensures the consistency of product quality. When it is necessary to repair or replace the electronic components, the presence of the installation groove makes the operation more convenient and accurate.

[0020] Optionally, a convex structure is provided on the inner surface of the inner ring, and the convex structures are evenly distributed along the setting direction of the inner ring for contacting the skin of the wearer.

[0021] By adopting the above technical solution, the uniformly distributed convex structures can increase the friction between the inner ring and the wearer's skin, making the ring not easy to slip off and improving the wearing stability. The convex structures can improve the air permeability when the ring contacts the skin, reduce the stuffiness and discomfort caused by long-term wearing, and allow the skin to breathe better. This design can disperse the pressure of the ring on the skin, avoid indentation or discomfort caused by excessive local pressure, and improve the wearing comfort. The tiny gaps formed between the convex structures and the skin contribute to the discharge and evaporation of sweat, keeping the skin dry. The uniformly distributed convexities can provide a certain massage effect, promote blood circulation, and especially have certain benefits to the health of the wearer's fingers when worn for a long time.

[0022] Optionally, a plurality of light-transmitting holes are provided on the inner ring, and the light-transmitting holes are arranged in an array for ensuring effective contact between the photoelectric sensor and the skin.

[0023] By adopting the above technical solution, the light-transmitting holes arranged in an array ensure that the photoelectric sensor can stably and effectively receive the light signals from the skin, improving the accuracy and reliability of sensor data collection. It ensures sufficient contact between the photoelectric sensor and the skin, enabling the smart ring to more accurately monitor physiological indicators related to light such as heart rate and blood oxygen. The setting of the light-transmitting holes helps to reduce the interference of non-skin light, improving the measurement accuracy and stability of the sensor. This design enables the smart ring to achieve effective signal transmission through the light-transmitting holes even when there is a certain gap or incomplete fit between the inner ring and the skin during wearing. The light-transmitting holes arranged in an array maximize the possibility of light passing through without affecting the structural strength of the inner ring, optimizing the performance of the smart ring. It facilitates the heat exchange between the sensor and the skin, reducing the impact of the local temperature rise caused by long-term wearing on the sensor performance and wearing comfort.

[0024] A smart ring includes the ring housing, and the smart ring accommodates electronic components through the cavity of the ring housing to achieve smart functions.

[0025] By adopting the above technical solutions, a safe, stable and reasonable accommodation space is provided for electronic components, ensuring the structural integrity and reliability of the smart ring, so that it can work normally in various usage environments. This design enables the smart ring to integrate a variety of electronic components, thereby realizing rich intelligent functions, such as health monitoring, positioning navigation, payment, etc., to meet the diverse needs of users. The optimized ring shell structure helps to improve the wearing comfort of the smart ring, reduce the discomfort caused by long-term wearing, and increase the user's willingness to use and wearing time. The detachable connection, stop structure, buffer design and other features of the shell facilitate the maintenance, upgrading and replacement of internal electronic components, extend the service life of the smart ring, and reduce the cost of use. The unique shell design can enhance the appearance and personalization of the smart ring, making it a fashionable accessory while being functional, attracting more users to choose to wear it. Through reasonable structural design, the overall weight and volume of the smart ring are effectively reduced, making it lighter, more compact, and easy to carry and use in daily life.

[0026] In summary, this application has at least the following beneficial effects:

[0037] The following further describes the present application in detail with reference to the accompanying drawings.

[0038] In this embodiment, referring to Figures 1-6 , a ring shell includes an outer frame 1 and an inner ring 2. The outer frame 1 and the inner ring 2 are detachably connected, which is convenient for users to quickly replace or repair internal electronic components according to needs, and at the same time ensures the overall structural stability of the ring shell. After the outer frame 1 and the inner ring 2 are enclosed, a cavity 3 is formed, and the cavity 3 is used to accommodate electronic components such as a processor, a memory, a sensor, and a control chip, so as to realize the intelligent function of the ring.

[0039] On opposite sides of the outer frame 1, mounting members 4 are provided, and the two mounting members 4 are used to mount watchbands, so that the ring can be matched with different watchbands according to the user's preference, increasing the flexibility and diversity of use. The mounting member 4 has a hollow design inside, forming a mounting channel 5, and the inner wall of the mounting channel 5 is provided with a hollowed-out avoidance opening 6. When the watchband is installed into the mounting channel 5, the avoidance opening 6 can ensure the smooth installation of the watchband and avoid interference with the mounting member 4, ensuring the smoothness and stability of the installation.

[0040] Specifically, the outer frame 1 is provided with a first notch 7, and the inner ring 2 is provided with a second notch 8 at the corresponding position. At both ends of the outer frame 1 near the first notch 7, first clamping members 9 are respectively provided, while at both ends of the inner ring 2 near the second notch 8, second clamping members 10 are respectively provided. When the outer frame 1 and the inner ring 2 need to be connected, only by aligning and clamping the first clamping member 9 and the second clamping member 10 together can the stable connection between the outer frame 1 and the inner ring 2 be achieved. This clamping method is simple and easy to operate, greatly improving the convenience of disassembly and assembly. Or the outer frame 1 and the inner ring 2 are installed or disassembled by using bolts.

[0041] Along the setting direction of the outer frame 1, a positioning groove 11 is further provided, and a positioning boss 12 is provided at the corresponding position of the inner ring 2. When the outer frame 1 and the inner ring 2 are connected, the positioning groove 11 and the positioning boss 12 will be closely matched, thereby ensuring the precise positioning between the outer frame 1 and the inner ring 2 and further improving the structural stability.

[0042] Embodiment 2

[0043] Refer to Figure 5 On the basis of Embodiment 1, the embodiment of the present application further provides more detailed designs of the ring shell. Specifically, a stop structure 13 is provided on the inner ring 2, and the stop structure 13 abuts against the inner wall of the outer frame 1. When the ring is subjected to external force extrusion, the stop structure 13 can effectively prevent the inner ring 2 from moving excessively relative to the outer frame 1, thereby protecting the internal electronic components from damage and enhancing the compressive resistance and use safety of the ring shell.

[0044] In addition, the connection method between the outer frame 1 and the inner ring 2 is further optimized to achieve detachable connection by magnetic attraction. Specifically, corresponding magnet blocks 14 are respectively provided on the outer frame 1 and the inner ring 2. When the outer frame 1 and the inner ring 2 are close to each other, the magnet blocks 14 will attract each other and automatically align, thereby realizing the rapid connection between the outer frame 1 and the inner ring 2. This magnetic attraction connection method not only further improves the convenience of disassembly and assembly, but also enhances the firmness and reliability of the connection.

[0045] Embodiment 3

[0046] Refer to Figure 5 On the basis of Embodiment 2, the embodiment of the present application further provides more functional designs of the ring shell. Specifically, the outer frame 1 is designed as a hollow structure, and a cavity 15 is formed by enclosing inside it. In this cavity 15, elastic members 16 are filled, such as flexible materials like silica gel and rubber. These elastic members 16 can undergo elastic deformation under the action of external impact force, thereby absorbing and dispersing the impact force and protecting the internal electronic components of the ring from damage. This design significantly improves the seismic performance and service life of the ring shell.

[0047] Meanwhile, on the inner surface of the outer frame 1 close to the cavity 3, there are also mounting grooves 17 for accommodating electronic components. These mounting grooves 17 are custom-designed according to the shape and size of the electronic components to ensure that the electronic components can be stably installed inside the ring housing. To further protect the electronic components, buffer insulation pads 18 are also provided in the mounting grooves 17. These buffer insulation pads 18 can play a buffering role when subjected to external force impacts and prevent faults such as short circuits between electronic components.

[0048] Embodiment 4

[0049] Referring to Figure 1 , on the basis of Embodiment 3, the inner ring 2, as the part directly contacting the wearer's skin, further has convex structures 19 on its inner surface. These convex structures 19 are evenly distributed along the setting direction of the inner ring 2 and can form point contacts with the skin during wearing, thereby reducing the contact area with the skin and improving the wearing comfort. At the same time, the gaps between the convex structures 19 can also promote air circulation and prevent the skin from feeling stuffy and uncomfortable due to long-term wearing.

[0050] In addition, referring to Figure 4 , a number of light-transmitting holes 20 are also provided on the inner ring 2, and these light-transmitting holes 20 are arranged in an array. When there are electronic components such as photoelectric sensors that need to work through light transmission inside the ring, the light-transmitting holes 20 can ensure that light can penetrate the inner ring 2 smoothly and reach the working surface of the photoelectric sensor, thereby ensuring the effective contact between the photoelectric sensor and the skin and accurate measurement. This design not only improves the measurement accuracy of the smart ring but also expands its application scenarios and usage value.

[0051] Embodiment 5

[0052] Referring to Figure 2 and Figure 5 , the embodiment of the present application also provides a smart ring, which includes the ring housing as described in any one of Embodiments 1 to 4. By accommodating electronic components through the cavity 3 of the ring housing, the smart ring can realize intelligent functions such as heart rate monitoring, step counting, and message reminder. Due to the adoption of the above ring housing design, the smart ring of the present application has been significantly improved in terms of structural stability, usage convenience, seismic performance, and wearing comfort, providing a more high-quality and intelligent usage experience for users.

[0053] Specifically, the electronic components in the smart ring are compactly and safely integrated through the cavity 3 of the ring housing. These electronic components can include but are not limited to heart rate sensors, motion sensors, communication modules, and microprocessors, etc., and they cooperate together to realize the diversified functions of the smart ring.

[0054] It also includes: A micro mainboard is carefully designed inside the ring, integrating core components such as a low-power microprocessor, a memory, and a power management unit. At the same time, a variety of functional sensors such as a micro camera, an accelerometer, a gyroscope, a heart rate sensor, an NFC chip, and a positioning module are integrated on the periphery.

[0055] The micro camera uses a fish-eye wide-angle lens. With the help of gesture recognition algorithms, it can accurately recognize and track the user's gestures, thus replacing the traditional mouse to achieve human-computer interaction. Gestures such as single-finger click to select, two-finger zoom, and fist clenching to confirm can all be recognized, which is extremely flexible and convenient.

[0056] The intelligent ring is built-in with an ambient light sensor, which can automatically adjust the camera exposure parameters according to the external light. Even in low-light environments, it can capture clear images. Combined with the OCR optical character recognition engine in the cloud, users only need to point the ring at the text to complete text scanning and recognition, easily realizing tasks such as business card scanning and textbook reading for word extraction.

[0057] The accelerometer and gyroscope are used to collect the motion posture information of the user's finger. Through pattern recognition algorithms, the user's writing intention can be judged. With a dedicated intelligent stylus, it can write words in the air to complete operations such as note-taking and handwritten signature. At the same time, it can also recognize large-scale movements of the user such as punching and swinging the arm, which are applied to game somatosensory operations.

[0058] The heart rate sensor uses photoplethysmography to calculate real-time heart rate data by monitoring the change in the volume of the user's finger artery blood vessels. Combined with the user's personal information such as age and height, it can evaluate the user's daily heart rate level and physical function status, and give sports health suggestions when necessary.

[0059] Integrating the NFC near-field communication module into the intelligent ring, it can be used as an access control card and a bus card. Users only need to bring the ring close to the card reader to quickly identify. It can also directly complete payments with the ring on the merchant's POS machine, saving the cumbersome steps of taking out the mobile phone to scan the code.

[0060] By integrating a GPS positioning chip and an electronic compass, it can record the user's geographical location and movement trajectory in real time. By calling the cloud map data, it can provide location services such as navigation and surrounding information query for the user. In addition, it can also be used as a positioning and monitoring device for the elderly and children to keep track of their locations at any time to ensure safety.

[0061] To improve the battery life of the intelligent ring, low-power devices are selected in terms of hardware, and the power management circuit is reasonably designed; in terms of software, an event-triggered mechanism is adopted. High-power-consuming components such as the camera and the positioning module usually remain in the sleep state and are only awakened for work when needed. Combined with the fast charging circuit design, the intelligent ring can be continuously used for a week after charging for several hours.

[0062] In summary, through the innovative ring shell design, the smart ring of the present application not only improves the structural strength and seismic resistance of the product, but also ensures the comfort of wearing and the convenience of use. At the same time, the highly integrated electronic components and powerful data processing capabilities endow the smart ring with excellent intelligent functions and usage experiences, making it an indispensable health management partner in modern life.
